Question

If binding energy of a nucleus is higher, it means
1. nucleus is more stable
2. nucleus is less stable
3. nucleus is absent 
4. nuclear is smaller

Answer 1

Correct Answer - Option 1 : nucleus is more stable

CONCEPT:

• Binding Energy of the nucleus: The energy that holds a nucleus together. or the energy required to disassemble a nucleus into its constituent protons and neutrons completely is called binding energy.
  • or the energy that would be liberated by combining individual protons and neutrons into a single nucleus is called binding energy.
• The higher the binding energy of the nucleus the more stable the atomic nucleus will be.

EXPLANATION:

• If a nucleus has more binding energy, it can hold the nucleus together more strongly which means the nucleus is more stable.
• So higher the binding energy, the more stable nucleus is.
• Hence the correct answer is option 1.
